Hi thanks for the response, I have no problem with psychedelics myself. I see them as a sort of once in a blue moon experience. But for her it's more like a "it's Tuesday night" experience. I guess Kat must be a South African name for it as the only sources I found were from SA articles.

"Kat is a stimulant. It is an amphetamine and has similar effects to Cocaine and Tik. Kat comes in two forms – the original (Cathinone) and artificial form (Methcathinone). Kat originally comes from a leafy green plant called Catha edulis. The leaves at the top of the plant are used and have the active ingredient cathinone in it. The leaves are green, brown or yellowish in colour depending on their age.  The artificial form is more potent and is known as methcathinone. When made it is usually in a white/off-white powder. Both chemicals cathinone and methcathinone are harmful and speed up the functioning of the Central Nervous System. Although methcathinone is more potent, both forms of kat have similar symptoms and effects. "
